Materialise Reports First Quarter 2025 Results

LEUVEN, Belgium--(BUSINESS WIRE)—April 24, 2025 -- Materialise NV (NASDAQ:MTLS), a leading provider of additive manufacturing and medical software and of sophisticated 3D printing services, today announced its financial results for the first quarter ended March 31, 2025.

Highlights – First Quarter 2025

· Boosted by 18.7% growth in our Materialise Medical segment, total revenue increased by 4.3% to 66,379 kEUR for the first quarter of 2025 compared to the corresponding 2024 period.

· Total deferred revenues from software maintenance and license fees increased during the quarter by 1,921 kEUR, to 48,870 kEUR.

· Adjusted EBIT improved to 646 kEUR for the first quarter of 2025 from (1,195) kEUR for the fourth quarter of 2024, but remained below the 2,656 kEUR of the corresponding 2024 period, reflecting the impact from macro-economic headwinds faced by our Materialise Manufacturing and Software segments.

· Net loss for the first quarter of 2025 was (535) kEUR, or (0.01) EUR per diluted share, compared to a net profit of 3,585 kEUR, or 0.06 EUR per diluted share, for the corresponding 2024 period.

· Driven by recurring positive free cash flow, our net cash position increased over the quarter by 6,716 kEUR to 67,736 kEUR.

CEO Brigitte de Vet-Veithen commented, “Amidst the current macro-economic and geo-political turbulence, we managed to grow our consolidated revenue by more than 4% in the first quarter of this year compared to the same period of 2024. At the same time, we significantly increased the deferred revenue carried on our balance sheet. Also in this quarter, our Materialise Medical segment continued to lead the way, with more than 18% revenue growth compared to the same period in 2024. Uncertain market conditions continued to weigh on our Materialise Manufacturing and Materialise Software segments, however. Although overall profitability in this year’s first quarter declined compared to the same period of 2024, we continue to realize operational efficiencies compared to the fourth quarter of 2024. At the same time, we further improved our net cash position while we continue to invest in sustainable growth, as detailed in our recently released 2024 Materialise Sustainability Report.”

2025 Guidance

Mrs. de Vet-Veithen concluded, “As already anticipated in our earlier guidance for the fiscal year 2025 issued in February, we expect uncertain macro-economic and geo-political conditions to impact the remainder of 2025 and in particular the second quarter, but we are convinced that the fundamentals of our business are solid and resilient. We therefore continue to expect to report consolidated revenue for the full fiscal year 2025 within the 270,000 to 285,000 kEUR range we communicated in February. We are also maintaining our Adjusted EBIT guidance of 6,000 kEUR to 10,000 kEUR for fiscal year 2025.”

Non-IFRS Measures

Materialise uses EBIT, EBITDA, Adjusted EBIT and Adjusted EBITDA as supplemental financial measures of its financial performance. EBIT is calculated as net profit plus income taxes, financial expenses (less financial income) and shares of profit or loss in a joint venture. EBITDA is calculated as net profit plus income taxes, financial expenses (less financial income), shares of profit or loss in a joint venture and depreciation and amortization. Adjusted EBIT and Adjusted EBITDA are determined by adding share-based compensation expenses, acquisition-related expenses of business combinations, impairments and revaluation of fair value due to business combinations to EBIT and EBITDA, respectively. Management believes these non-IFRS measures to be important measures as they exclude the effects of items which primarily reflect the impact of financing decisions and, in the case of EBITDA and Adjusted EBITDA, long term investment, rather than the performance of the company’s day-to-day operations. The company also uses segment Adjusted EBITDA to evaluate the performance of its three business segments. As compared to net profit, these measures are limited in that they do not reflect the cash requirements necessary to service interest or principal payments on the company’s indebtedness and, in the case of EBITDA and Adjusted EBITDA, these measures are further limited in that they do not reflect the periodic costs of certain capitalized tangible and intangible assets used in generating revenues in the company’s business, or the changes associated with impairments. Management evaluates such items through other financial measures such as financial expenses, capital expenditures and cash flow provided by operating activities. The company believes that these measurements are useful to measure a company’s ability to grow or as a valuation measurement. The company’s calculation of EBIT, EBITDA, Adjusted EBIT and Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies. EBIT, EBITDA, Adjusted EBIT and Adjusted EBITDA should not be considered as alternatives to net profit or any other performance measure derived in accordance with IFRS. The company’s presentation of EBIT, EBITDA, Adjusted EBIT and Adjusted EBITDA should not be construed to imply that its future results will be unaffected by unusual or non-recurring items.
